hello AIR
thank you for JadeLib and for the very permissive license
just a couple of notes, I had to comment out the Windows specific equates in the makefile to build the lib using msys2
in the example demo.cc, INSTR(mystring,"is") gives 2 as the answer, where mystring = "This is a string."
FreeBasic and QB64 give 3 as the answer.
